Outline of Final Research Achievements

Wireless mesh networks are considered as an efficient candidate for a substitution of communication infrastructure in disaster situations. Such a network is suffered by mutual interferences between nodes since all nodes are reachable. We studied a cross layer processing to exploit this overreach by using beam/null control at each node. Specifically, beam/null control and its experimental test using USRP in the layer 2 were carried out. In addition, we clarified that the alternative routing with beam/null control in the layer 3 improved the throughput performance.
